Abstract |
Recently, solution processable organic light-emitting diodes (OLED) have emerged as alternative to vacuum processed OLEDs due to the low-cost, large area, and flexible display applications. However, it is still difficult to prepare all the layers in multi-layered OLEDs via solution processing since bottom layer can be dissolved during the deposition of the upper layer. As a solution, crosslinking system has been considered as one of the most effective methods to make insoluble from many common organic solvents without any complicated fabrications. A new side-chain hole transport polymer, X-TPACz which contains thermally crosslinkable side chain unit, was synthesized via facile addition polymerization. Using the UV-vis absorption spectroscopy, curing conditions were optimized by investigation in terms of curing temperature and curing time. Using X-TPACz as hole transport layer, high external quantum efficiency with low turn on voltage was obtained in application of solution processable OLED. |
